P0335

I am getting this error on a v6 4.0 1GR-FE also 50k mileage on motor
There is no effect on the Tundra truck what so ever. It just seems like a glitch

checked wiring on CKP sensor - looks brand new. Changed CKP sensor with new one and I still get cel P0335
checked voltage and proper voltage detected.

Does anyone have any suggestions of what to look for

Does it have dirty starts sometimes? For example, it starts every single time but maybe every 3-4 starts it will stutter very softly to where you almost don't even notice before it fires up? Kind of a shot in the dark, and I know it says "Circuit Malfunction", but it's possible that the timing chain tensioner could be failing and maybe the chain jumped a tooth. If the timing is off by one tooth, you may never notice driveability issues, but the electronics will notice the timing difference between the crank sensor and cam sensors and toss a code... food for thought.

Did you check the voltage at the sensor or the battery voltage?
